While the number of people working in construction, manufacturing, and several other major industries held steady last month, the American healthcare sector continued to grow, adding 37,000 jobs in June, the U.S. Bureau of Labor Statistics (BLS) announced today.

That figure outperformed the average number of healthcare jobs gained monthly all of last year and so far this year, the BLS announcement noted. (The economy added 32,000 healthcare jobs per month, on average, in 2016 and 24,000 jobs per month in the first half of 2017.)

The number of people working in hospitals grew by 12,000 in June, but employment in ambulatory healthcare services grew even faster, with 26,000 jobs added. This reflects a decades-long shift in how and where physicians and their staffs care for patients. More services are being offered in outpatient settings, and some community hospitals, especially in rural areas, have fallen on hard times.

The shifting landscape impacts everything from the way clinics ensure basic environmental cleaning to how health systems strategize with regard to employment and market share. And, of course, it impacts the way OSHA and other regulatory bodies go about protecting workers and the public.

Across all industries, the U.S. economy added 222,000 jobs in June, beating both expectations and recent monthly averages. This bird’s-eye view of the economy, however, misses much of the nuance on the ground level, where many hiring managers are on unsure footing. Healthcare employers, especially, are watching Washington, where the Republican-controlled Congress and White House are struggling to finalize a budget and healthcare plan, as The New York Times reported.

“This is an unprecedented level of political uncertainty,” William E. Spriggs, chief economist for the AFL-CIO union, told the Times. “That is creating a drag on the economy.”

Hiring at medical labs and nursing homes, for instance, has been on the decline, Spriggs said, attributing the slowdown to the number of unknowns in the future of the U.S. healthcare system.
